Electrical plug connector

Abstract

An electrical connector includes a connector housing and a printed circuit board with two sets of contact elements. The first set of contact elements is located on the front face of the printed circuit board and protrudes into an opening in the plug connector housing. The second set of contact elements is located on the rear face of the printed circuit board. The contact elements of the second set are configured to form insulation-displacement contacts. The plug connector also includes a cable manager which has a continuous opening and is configured on the front face with guides for cores or wires which are intended to make contact with the insulation-displacement contacts. The guides in the region of the insulation-displacement contacts are configured with recessed receiving elements or holders for the insulation-displacement contacts, and the cable manager can be latched to the plug connector housing.

       10. The electrical plug connector system of  claim 9 , wherein the second side of the cable manager defines wire guides at which the wire cores are positioned. 
     
     
       11. The electrical plug connector system of  claim 10 , wherein the cable manager also defines recessed holders at the wire guides, the recessed holders being configured to receive insulation displacement contacts to aid in aligning the insulation displacement contacts with the wire cores at the wire guides. 
     
     
       12. The electrical plug connector system of  claim 1 , wherein the tool further comprises a cable clamp including a jaw arrangement that cooperate with a closure element to encircle a portion of the cable. 
     
     
       13. The electrical plug connector system of  claim 12 , wherein the closure element includes limbs defining latching grooves that are configured to retain the closure element on the jaw arrangement. 
     
     
       14. The electrical plug connector system of  claim 13 , wherein the jaw arrangement includes a first jaw and a second jaw arranged on a base, the first and second jaw being connected by a spring with which the latching grooves of the closure element interact to retain the closure element on the jaw arrangement. 
     
     
       15. The electrical plug connector system of  claim 14 , wherein the base defines elongated holes through which a portion of the spring can be inserted. 
     
     
       16. A method for assembly of an electrical plug connector system including a plug connector housing, a cable manager, and a tool, the plug connector housing including insulation displacement contacts that are electrically connected to plug contact elements, the method comprising:
 arranging wire cores of a cable at the cable manager including passing the wire cores through an opening in the cable manager, pressing the wire cores into associated guides of the cable manager, and cutting off excess length of the wire cores; 
 positioning the cable manager on the plug connector housing to form a connector arrangement including aligning recessed holders of the cable manager with the insulation-displacement contacts of the plug connector housing and seating the cable manager on the plug connector housing with the insulation-displacement contacts extending at least partially into the recessed holders; 
 sliding at least a portion of the connector arrangement into a cavity defined by the tool including aligning an inclined surface defined by the cable manager with a complementary inclined surface defined by the tool and sliding the connector arrangement laterally relative to longitudinal axes of the insulation-displacement contacts to form the electrical plug connector system.
